It may seem like a good idea to mount the IT cabinet 8 feet off the floor (it won't get splashed on and nobody will hit their head). DO NOT DO IT. The floor WILL be greasy, and the ladder will also be greasy. Put the IT cabinet in the office, a couple of feet off the ground if you need it to be mopped under, but not high enough to need a ladder.

Also, to anyone choosing a half-size wall-mount cabinet: There is at least one model where the equipment is vertical parallel to the back wall instead of the standard layout. IT IS CRAP! There is no access to any of the equipment not in the front row. Choose any standard horizontal layout cabinet.
